.isubject of the King of Great Britaimlr esid ing at Thru Valley, Yalecounty, and Province of British Columbia, Oana'da,have invented anddiscovered certain new anduseful Improvements in Combined Saw Sets, andGages, of which the 'followingis a specification.

My invention relates to a combined saw set and gage and its objects areto provid'e a device of the type described that may be readily graspedand held in the handof the user during the setting and gaging operationsand to enable such operations to be effected while the operative face,of the device occupiesthe same plane relative. to the face of the sawblade, thereby facilitate ing the operation, and enabling a simpler andmore compact form of device to be employed. 'I 1 With these endsandothers in view my invention is embodiedlin preferable formin thedevice hereinafter described and illustrated in the accompanyingdrawings.

In the drawings Figureil is' a side" view in elevation, showing a sawinposition to be set; Fig. 2, a similar view showing the saw in gagingpositionand Fig. 3," a front" view in elevation. v i T Referring to thedrawings, \1 is a solid block, preferably of substantially cubical formand of a size .an dgthickness to render it capable of being easilygrasped in the hand of the saW fitter and'galso capable of offeringsubstantial resistance to'the shock of the setting blow; Thisblockisprovided' 1 on the operating face: thereof with a flat sur-II face 2,adapted to .eXtend in avertical plane when the block is in the settingand gaging f positions. From -the ,upper edge of this face eXtendsto theupper edge of the block,

A v a beveled face 3, constituting an anvil surface and on which thesawis adapted to be set at theproper angle. -1

An L-shaped' bracket ismounted on the upper horizontal face.of.theblock, :one arm 4 thereof being secured, preferablybya screw, tothe block and the other arm 5 eX-' tending from the edge oftheganvilsurface vertically upward in a plane parallel to'the plane of the flatface2. M

Mounted in the arm 5 near the upper end,

sistin'g of'a screw 6 having a knurled head 7. -fl-he end of the screwprojects through" the'arm 5 and on the screw is mounted a =lock-nut 8whereby, after the screw has been adjusted to the proper degreeofprojection, it may be locked rigidly in such position.

" In thefiat portion 2 of the block are H I mounted adjustable headlessscrews 9,;spa'ced' I- apart .sufiiciently to afford, a support for 5thesaw blade and also constituting regulable set gage members.

The block is cut away at10 ,65 from the U lower edge of the block, thisrecessed part, '1 J01n1ng the fiat bearing surface 2. .Abracket e 11ismounted in the lower face ofthe block 7 andfi's provided with anattaching arm 12,

and a gagingarm 13, the latter extendingg vertically from the lower edgeof the block. I

This arm 13 is provided at its end with a laterally'projecting boss orprong llj form 1113; a fixed set-gage member.

In the use ofthe device, the block is. held v in the left. hand oftheoperator with the saw blade bearing against the fiat surface I Z'andatoothj projecting over the anvil .surface "Then the tooth isjstruck witha hammer tobend it over the anvil and give 1t thedesired set. Then bymerely moving the block downward in the same plane until;

the'point of the tooth is brought opposite the screw 6, the prong andthe gage screws 9l arecarried against the face of the blade leveling theblade and if the set is correct,

the point of the tooth will just touch the outer end of the screw 6,which has been set and locked to a predetermined degree of projection If.the'setis not correct the I tooth is bent backor down. Y

blade bears directly against the flat-surface I 2 of the block,thegaging screws 9' may be In order to enable the gagingjmembers I screwedoutwardly-so as to'project beyond i the surface of the block to thedesired degree, whereupon Twhen the sawblade'is placed against the'prong14: and screws 9.

and leveled thereon, the tooth edge: of the blade will be pro ectedoutwardly from the I block to a greater degree;

The angle of set is determined the ex} tent of projection ofthe gagescrew f I claim is: I

A combmed saw set and gage having a solid hand grip block; one facethereof forming "the bearing face forthe saw and having an anvil portionformed on said face, arms projecting in opposite direct-ionsfrom saidblock in line with said face, one of said arms having a bearing memberfor the sawblade and the other arm provided with an adjustable gagescrew, in combination with headless adjustable set screws mounted in thesolid block and-adapted to be moved in and out With respect to saidbearing face, substantially as described.

In Witness whereofllhave'hereunto set my hand and seal-at Thru Valley,B. 0., this ninth'day of June, A. DJhineten hundred and-thirteen. I
